The Pasco software (in this case Saparkvue) makes recording this a breeze, creates the tables and graphs so that the data can the analysed easily.
A small amount of the chemicals are used ( approximately 6ml per experiment. The cuvette is filled with the required mixture and the placed in the calorimeter. This calorimeter records all the wavelengths at the same time so I don't have to worry about selecting the correct one, but simply the best one at the end of the experiment.
Before the experiment is started it is necessary to calibrate the colorimeter but a cuvette of pure water, then it is simply a task of placing the solution to be examined in the cuvette and clicking start
The results can then be exported to word with any analysis. This system seems so much better value for money than other systems I have used.
